Definitions
- the present invention relates to the environment of contact lenses and their safety specifically using the method of elevation and de-elevation within sealing means and with contact lens solution in place prior to opening providing an extremely safe, easy and cost effective apparatus for the contact lens user.
- Eye conditions come in different forms like: Myopia (also called short sightedness), Hyperopia (also called hypermetropia or long-sightedness), Presbyopia which is the loss of focussing ability of the eyes, Astigmatism in which the cornea at the front of the eye is oval instead of round, and others like Keratoconus, Meibomian Gland Dysfunction and Computer Vision Syndrome to name but a few.
- contact lenses are available in the marketplace including Disposable contact lenses, Leave-in (extended wear) contact lenses, Gas permeable contact lenses, Hard and Soft contact lenses. These can then be made to the prescription of the eye wearer. Even a tint can be added and in the field of fashion contact lenses are available in all sort of forms. In recent years exiting new developments in the practice of contact lenses have included new materials for soft contact lenses that allow more oxygen to the eye, enabling a more comfortable fit with longer wearing times.
- contact lenses will still be potentially able to collect harmful contaminants that may make their use uncomfortable or make their prescription not work perfectly. These contaminants may include the fluid from the eye, small deposits from soaps, cosmetics, airborne dust and other matter. Therefore the need to be able to remove these contaminants and keep the contact lens comfortable for users will always be present.
- US 3955726 A discloses a contact lens storage locket which would not be cost effective to make and would include the fishing out action of the contact lens from the container within the locket and be very tricky to use
- EP 0694017 A discloses the need for a container which might include a sliding action or adhesive to keep it watertight.
- EP 0542686 Al (Ciba-Geigy), EP 0542686 Al 5 US 3822780 A and US 4328890 A (Thomas et al) either include detachable parts, rely on external addition of solutions or the need once again to fish about to find lens.
- Document EP 0389418 discloses an elevating member 21, a reservoir 15, a sealing means (screw threads) and a lid 11 communicating with a channel (screw threads) on the reservoir however, there is no mention in this document of the elevating member 21 being self-elevating or of the contact lens solution being prevented from escaping prior to the first opening of the apparatus. In each instance where the elevating member is shown a finger is required to provide the force necessary to elevate it.
- Document JP 2001046134 discloses a member 4 and a reservoir 6 however, there is no mention of a sealing means on at least one Hd communicating with a channel on a reservoir whereby contact lens solution is prevented from escaping prior to the first opening of the apparatus.
- Document DE 4415003 shows a member 2, a reservoir 62 and a sealing means 74, 79 & 69 however, there is no mention of the member being self- elevating indeed it can clearly be seen from the figures that the member 2 is elevated by means 4. Furthermore, there is no mention of the sealing means communicating with a channel on the reservoir or of the contact lens solution being prevented from escaping prior to the first opening of the apparatus.
- Document US 3460552 discloses a member 19, a reservoir 13 and a sealing means 11 however, there is no mention of the member 19 being self- elevating, indeed elevation of this member is activated by a separate spring 59. Furthermore, nothing is mentioned of the sealing means 11 communicating with a channel on the reservoir or of the contact lens solution being prevented from escaping prior to the first opening of the apparatus.
- Document US 3646672 discloses a member 36, a reservoir and a sealing means 32 on a lid. There is no mention of a self-elevating member as this device utilises the force of a coil spring to elevate the member 36. There is also no mention of a sealing means communicating with a channel on the reservoir or of the contact lens solution being prevented from escaping prior to the first opening of the apparatus.
- Document US 4942959 discloses a member 30, reservoirs 14 & 16 and a sealing means 56/58 on a lid communicating with a channel on the reservoir however, there is no mention of the member being self-elevating as it is clearly shown that the member 30 is elevated by its interaction with the fluid 38 furthermore, there is no mention of the contact lens solution being prevented from escaping prior to the first opening of the apparatus.
- Document DE 10053798 discloses a member 24 and a reservoir 30 however, there is no mention of a sealing means communicating with a channel on the reservoir or of the contact lens solution being prevented from escaping prior to the first opening of the apparatus.
- the present invention is directed to the field of contact lens storage devices which only make use of a single solution rather than combinations of chemicals and focuses on the problem encountered by contact lens users, having forgotten their lens cases and/or their solution, that being that they, having set off on a journey for example, find that they need to temporarily remove their lenses but have not got a safe and hygienic place to store their lenses.
- a contact lens user would simply use the apparatus according to the present invention rather than using expensive and bulky lens cases, containers of solution and perhaps catalysts.
- Featured within the invention is the integral lids and the contact lens solution partially filled under a seal and again sealed in the main apparatus. This is to provide security and safety.
- the advantages of the invention are mainly its overall safety and to decrease the use of finger contact with the lens and decrease the intricate manoeuvres normally associated with the removal and insertion of contact lenses and at the same time keeping the contact lenses stored hygienically safe in a small compact unit which does not have parts that are detachable affecting the safety of the apparatus. It should be noted that this invention is not to replace the need for contact lens cases or solutions or even contact lenses themselves. This invention is a stand alone method geared towards the safety of the contact lens user when they have forgotten their spare lenses, case or solution. It is also intended to be used where space and safety are a priority. This could be on an Aircraft or Ship to name only two examples out of many.
- Figure 1 shows the contact lens safety apparatus 1 in an open aspect, prepared to receive at least one contact lens. It can be seen that the apparatus 1 is comprised of a resilient member 5 and a plurality of receiving members 10.
- the resilient member 5 has a framing section 15 and a plurality of lids 20 which are substantially circular in form and are hingedly attached to the framing section 15.
- the hinging nature of the attachment is achieved by providing an area 25 of reduced thickness between the framing section 15 and the lids 20.
- the lids 20 have an outside face 30 and an inside face 35.
- the inside face 35 of the lids 20 include an annular section 40 coaxial with the lids 20 and protruding from the inside face 35.
- the annular section 40 having an inner diameter 45 and, an outer diameter 50 that is circumscribed by a sealing means 55, which extends from the outer diameter 50.
- the framing section 15 includes a plurality of reservoirs 60 having a bed 65, scalloped sides 70 and a top edge 75.
- the top edge 75 of the reservoirs 60 is substantially circular.
- the scalloped sides 70 include a first channel 80 and a second channel 85 (shown in figures 2 & 3).
- the first and second channels extend around the perimeter defined by the scalloped sides 70 to form two independent unbroken channels and are sited proximal to top edge 75.
- First channel 80 being sited most proximal to the top edge 75 in order to receive the sealing means 55 when the lids 20 are closed.
- the receiving member 10 defines a substantially circular bowl 90 having dimensions suitable for accommodating a contact lens.
- Bowl 90 includes a base 95 and a substantially circular wall 100, which extends away from the base 95.
- the wall 100 is similarly shaped to the scalloped sides 70 of the reservoirs 60 and include, around its circumference a plurality of elongate slots 105 extending from a site proximal to the base 95 towards a site proximal a rim 110 of the bowl 90.
- the bowl 90 further includes an orifice 115 in its base 95 coaxial with the bowl 90.
- a plurality of resilient means 120 are provided equidistant around the rim 110 of the bowl 90.
- the resilient means 120 take the form of an inverted U and are connected to each other via an annulus 125, the annulus having an inside 130 and an outside 135.
- the outside 135 of the annulus 125 being configured to be accommodated by the second channel 85 thereby securely holding the receiving member 10 in position within the reservoir 60.
- the annulus 125 has a top surface 140 on which one leg 145 of the resilient means 120 is fixed.
- the leg 145 of the resilient means 120 does not extend over the full width of the annulus 125 but stops short of the scalloped sides 70 of the reservoir 60.
- the reservoir 60 will be partially filled with contact lens solution 150 prior to the first opening of the contact lens safety apparatus 1 however, this solution 150 has not been shown in figure 1 to aid clarity.
- the lid(s) 20 are moved from a closed position, (shown in figure three with the lid removed for clarity) to the open position as shown in figure 1 by hingedly rotating them about the area 25.
- the resilient means 120 is in an elastically bent position thereby holding the receiving member 10 submerged in the solution 150.
- Sealing means 160 is in place on 125 as can be seen in figure 3.
- the resilient means 120 Upon moving the lids 20 to the open position then removing sealing means 160 the resilient means 120 elastically deforms to return to its relaxed state as can be seen in figure 2.
- This relaxing of the resilient means 120 elevates the receiving member 10 to a point above the solution's surface 155 where the user may place a contact lens safely into the substantially circular bowl 90 of the receiving member 10.
- the lids 20 When the user has placed their contact lens(s) safely into the bowl 90 they may then move the lids 20 to a closed position, in doing so the lids 20 initially contact the inverted U shape of the resilient means 120.
- the resilient means 120 undergoes elastic deformation, stressing it and causing the receiving member 10 to become submerged under the solution's surface 155.
- the orifice 115 in the base 95 of the bowl 90 is flooded with the solution 150.
- Solution 150 also floods through the plurality of elongate slots 105 causing any contaminants or debris on the contact lens to be washed off and to sink to the bed 65 of the Bowl 90.
- the lids 20 are further pressed into the closed position thereby engaging the sealing means 55 with the first channel 80 to maintain a releasable seal around the perimeter defined by the scalloped sides 70.
- the resilient means 120 having a elastically deformable nature could also be at least in the form of a spring.
- maximum resistance between the contact lens safety apparatus and contact lens and solution will preferably occur.
- the material could also be able to illuminate to aid in its safety in the dark. Having the material partially transparent could also be an advantage to see contents are present, especially if the lens was tinted or cosmetic.
- the self-elevating member could function without the contact lens present.
